Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- other: Expert statement
- Adequacy of study:
- key study
- Study period:
- 2010 - 2011
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Remarks:
- Functional groups of FeS were considered in the assessment.
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Qualifier:
- according to guideline
- Guideline:
- other: UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 6.1.2
- Principles of method if other than guideline:
- According to the UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 6.1.2 the classification procedure for inorganic substances need not to be applied if the substance does not contain any oxygen or halogen atoms.
- GLP compliance:
- no
- Key result
- Sample tested:
- other: test substace itself by assessing the functional groups.
- Parameter:
- other: assessing the functional groups.
- Remarks on result:
- not measured/tested
- Remarks:
- FeS is not capable to act as an oxidizing substance. Sulfur itself is not an oxidizer but is oxidizable itself (e.g. Sulfur dioxide or Sulfur trioxide). If the FeS, for example, decomposed due to a fire, oxidation of the Sulfur would clearly take place in all probability.
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- FeS has no oxidizing properties
- Executive summary:
According to the chemical structure and the additional classification considerations given in the in the Regulation (EC) No 1272/2008 (CLP) Chapter 2.13.4. and the UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 6.1.2 it can be excluded beyond reasonable doubt that FeS has oxidising properties.
Reference
According to the chemical structure and the additional classification considerations given in the in the Regulation (EC) No 1272/2008 (CLP) Chapter 2.13.4. and UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 6.1.2 it can be excluded beyond reasonable doubt that FeS has oxidising properties.
Oxidizing materials are either liquids or solids that readily give off oxygen or other oxidizing substances (such as bromine, chlorine, or fluorine). They also include materials that react chemically to oxidize combustible (burnable) materials; this means that oxygen combines chemically with the
other material in a way that increases the chance of a fire or explosion or at least it causes an acceleration of burning. The reaction may be spontaneous at either room temperature or may occur under slight heating. Oxidizing materials can be severe fire and explosion hazards.
Examples for groups of common oxidizing materials:
bromine
bromates
chlorates
chromates
dichromates
hydroperoxides
hypochlorites
inorganic peroxides
ketone peroxides
nitrates
nitric acid
nitrites
perborates
perchlorates
perchloric acid
permanganates
peroxides
peroxyacids
persulfates
The property of a substance to act as a fire accelerating oxidator is therefore dependent on the ability to oxidize combustible materials and herewith to react exothermically.
FeS is not capable to act as an oxidizing substance. Sulfur itself is not an oxidizer but is oxidizable itself (e.g. Sulfur dioxide or Sulfur trioxide). If the FeS, for example, decomposed due to a fire, oxidation of the Sulfur would clearly take place in all probability.
Description of key information
FeS has no oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
According to the chemical structure and the additional classification considerations given in the in the Regulation (EC) No 1272/2008 (CLP) Chapter 2.13.4. and the UN “Manual of test & Criteria”, Appendix 6, Screening Procedures, point 6.1.2 it can be excluded beyond reasonable doubt that FeS has oxidising properties.
FeS is not capable to act as an oxidizing substance. Sulfur itself is not an oxidizer but is oxidizable itself (e.g. Sulfur dioxide or Sulfur trioxide). If the FeS, for example, decomposed due to a fire, oxidation of the Sulfur would take place.
Justification for classification or non-classification
According to the chemical structure and the additional classification considerations given in the in the Regulation (EC) No 1272/2008 (CLP) Chapter 2.13.4. it can be excluded beyond reasonable doubt that tin disulfate has oxidising properties.
Therefore, classification and labelling are not needed.
